OpenSSL 安全级别

¥OpenSSL security level

OpenSSL 库强制执行安全级别以控制加密操作的最低可接受安全级别。OpenSSL 的安全级别范围从 0 到 5，每个级别都施加更严格的安全要求。默认安全级别为 1，通常适用于大多数现代应用。但是，一些旧功能和协议（例如 TLSv1）需要较低的安全级别（SECLEVEL=0）才能正常运行。有关更多详细信息，请参阅 OpenSSL 安全级别文档。

¥The OpenSSL library enforces security levels to control the minimum acceptable level of security for cryptographic operations. OpenSSL's security levels range from 0 to 5, with each level imposing stricter security requirements. The default security level is 1, which is generally suitable for most modern applications. However, some legacy features and protocols, such as TLSv1, require a lower security level (SECLEVEL=0) to function properly. For more detailed information, please refer to the OpenSSL documentation on security levels.
